Application filed January 20, 1915. Serial No. 3,2%.

To @ZZ whom z'z may concern:

lle it known that l, Liconn) ALANcHiKorr,

' a citizen of the United States, residing at lexs ond-step in the unlocking operation. 3S

Philadelphia, in the county of Philadelphia and vitatc of Pennsylvania, have invented ycertain new and useful Improvements in: Combination-Padlocks7 oi' which the following is a specification.

My invention relates to improvements in combination padlocks, the object ofthe in` vention. being to provide an improved arrangement of pivoted tumbler-s controlled by an improved arrangement of rotary and longitudinally movable plungers for operating a springpressed bolt to release the shackle and allow the latter to be thrown open by its spring.

A further object is-to improve upon the construction 'set 'forth in Patent No. 1,123,061 granted to me ecember 29th, 1914, on an improved padlock. Y

lilith these and other objects in view, the invention consists in certainv novel features oil construction and combinations and ar-v rangements of yparts as will be more fully hereinafter described andpointed out in the claims. j

In the accompanying drawings: Figure l is a view in elevation with the casing front removed showing the parts in normal locked position. VFig. 2 is a similar view illustrating the frst step in theunlocking operation.

Fig. 3 is a similar View illustrating the secl Fig. is a similar view illustrating theA third step which completes the unlocking operation.

Fig. 5 is a view on an enlarged scale illus- 1 trating my improved arrangement ot tumblers showing in dotted lines the coniorma tion of the respective tumblers t3 is a view in transverse section on the line 6 6 of Fig. 5. and Figs. 7, 8, and 9, are views in elevation on thesame scale as Fig. 5 illustrating the respective tumbler-s. u

1 represents the lock casing which'is made in two half sections, but for convenience of description, I shall refer to one-half section as the body oi` the casing 1', and the other 'half section as thefront 2. These parts are securely riveted together so as to prevent access tothe interior of the casing.

3 is the shackle pivotally secured to the casing at one end by means of a pin l and engaged by a spring 5 within the casing to throw the shackle to open position. In the free end of the shackle 3, a recesso is protively.

vided to' receive a locking bolt- 7, the latter guided in a bearing 8 and held in locked position by ay coiled spring 9. i' The bolt 7 and the freeend o' the shackle 3 or beveled aselearly shown, so that the shackle when forced into closed position, will displace the bolt and permit the' latter to spring into the recess G and'locl'without any manipulation of the tumblers herein-'1 65 after described.

10, il, and l2 represent my improved tumblers, each of which is provided with an opening 13 to receive a pivot pin 14;, and

have rotary or pivotal mounting on'the pin. -76

The tumbler which is located adjacent. the back wall of casing l, is provided with a. bifurcated finger 19- which is positioned in an annular groove 15 in the locking bolt 7 and operates to withdraw the bolt when the 75.

tumbler is given sufiicient pivotal movement.

Thistumbler is held in itsA normal position by means of the spring 9 on the bolt 7, and

the movement of the tumbler overcomes the y tension. of the spring to withdraw the bolt.-

The tumbler 11 is locatedin front of tumbler 10, and is provided at one end with a curved.. tongue 1G. The tumbler 12 is located against the outer face of tumbler 11, and.

is provided at one end with a. curved tongue S5 17. ,il spring 18 is coiled between its ends around the pivot 14. This springbears at one' end against the tongue 16 of tumbler 11., and at its other end against the tongue 17 vof tumbler 12, serving the double function *of holding these tumblers 1n their normal positions.

The tumblers 10, `11, and l2 are moved' kby fourplungers 20, 21, 22, and 23 respec- These plungers are mounted in lopenings 2d in the bottom of casing l, and 'falso in openings 25 in a guide bar 26, the

lattersecured in the casing adjacent the bot- 'toni'thereof as .clearly shown. These plun 'gersv are each provided with coiled springs 100 127 located around. the same between the guide bar 26und an annularshoulder 28 on the The springs therefore press the ,plungers longitudinally in a downward direction, and ythe shoulders28serve 'as 105 bearing points for the ends of the springs and also limit the outward or downward movement Vof the plungers by engagement with the bottom of the casing 1.5. Plungers 20 and 21 are longenthan plungers 22 and 110' 23, and at their inner ends are provided with laterally projecting lingers 29 and 30 are rounded e@ drawal of the bolt, however, the tumblers 11 and 12 are of such a shape that they normally operate as shutters topi-event the turning movement of pllmgers 20 and 21, and must be moved by -the plungers 22 and 23 before plungers 20 and 21 can be turned Ito. operative position, and` such operation must be in proper succession'. Normally, the parts are in the positionshown ,inFigs 1 and 5.1' That is to say, thezplunger 23 is located under lug 31, plunger 22 is located under tongue 16, plunger 21 is located be- 'sidey or in frontof tumbler 12, the latter in vsuch position as' to prevent therotary movement 'of the plunger to position the tongue under the wallv 32 of tumbler 10. Plunger 20, at its inner end, iis located in front of tumbler 11, the latter preventing turning movement of the plunger to position the finger 29 under the wall 33 ofrtumbler 10.

To operate the lock, plunger 23 is first moved upwardly as shown in Fig. 2, thereby moving tumbler 12 on its pivot and moving said tumbler out of the Way of. 'finger-30. The next operation4 is to turn 'the plunger 21 so as to position the finger- 30 under the wall 32 of tumbler 10. The next operation is `to press the plungers 21 and 22 upwardly, as shown in Fig. '3. 'Ihe upward movement of plunger 2l by reason o the engagement of finger 30 with wall 32.y moves the tumbler 10 on its pivot, but not far enough to entirely withdraw the bolt as shown in Fig. 3. The upward movement of plunger 22, by reasonof its en agement with the tongue 16, causes the tum ler 12 to swing on its pivot and move out of the way of finger 29. The next operation is to turn the plunger 20 so as'to' position the finger 29 under the wall 33"oftumblerv 1.0. The' final operation isto press upvifardly'plunger 20.. which moves tumbler 10e-.to complete the Withdrawal of the ybolt and release the shackle as shown clearly in Fig. 4. When the plungers 20 and 2,1 are given a quarter turn tmove them out of the npath of the tumblers, the spring 18 and the spring 9 re- 'turnl the tumblers' to normal position, while the springs 27 return the plungers to nor- ,mal position; and as soon as the shackle is closed,y it will be automatically locked by the spring-pressed bolt 7.

:ing adaptedto engage the free end of the `I isto be understoodthat all of the plungers are capable of rotary as well as longitudinal movement,l and in order to release the lock, it is necessary for the operator t0 know just how to manipulate and the order of operation of the several plungers. This 70 may be varied so as to change the combination of the lock, and hence the invention isA not limited to the precise shape of the tumblers or vthe precise construction and operation of the plungers, but I consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scfpe of the appended claims.
